Servo Motor Controllers

Can be operated in stand-alone operation

Pittman Motors, a business unit of AMETEK Precision Motion Control, is introducing its latest offering: the BGE Series of Servo Motor Controllers, a family of compact 4-quadrant positioning motion controllers with integral output stage to control Pittman brushless and brushed DC motors.

The motion controllers can be employed in stand-alone operations with digital or analog IO or as a slave in a CANopen network with device profile DSP 402, protocol DS 301. The family of motion controllers is rated from 12VDC to 60VDC input voltage and 4 amp to 20 amp continuous output current.

The BGE Series controllers are suitable for use with Pittman brushless or brushed DC motors. Information about the motor's rotor position can be supplied to the positioning controller by an encoder or integrated Hall sensors contained within a brushless motor. The controls incorporate protection against over-voltage, low voltage and excessive temperature.

If 4-quadrant digital speed control is desired, the control can be commanded to run in either direction, stop and hold with torque, and stop without torque (coast) through digital inputs. Other inputs can switch between programmed speeds or allow for a variable analog speed reference.

Accel/decal ramps for the motor also can be programmed. The control offers the capability for a motor to function as a stand-alone or programmed servo, which interfaces to the rest of the machine via digital and analog IO.

The BGE Series electronic controllers offer many different modes of operation to choose from, such as analog or digital torque control, analog or digital speed control and digitally selectable position control (relative, absolute, and modulo). The controls incorporate protection against over-voltage, low voltage and excessive temperature.

Designed for volume OEM applications, BGE Series electronic controllers offer a design alternative for restricted space applications where the additional length of an integral control motor may not be feasible. They also can be encapsulated to provide additional protection in extreme environmental conditions.

If only speed control is required for an application, the BGE 3004A, a cost-optimized 1 quadrant controller, is available. BGE controllers are available from stock at the Pittman Express E-Commerce store.
